Since there is no report of daily walking activity of Korean, authors studied on normal adult daliy walking activity in korean of various kinds of occupation, personal life and patients. Total 134 cases were studied and in which there were 10 patients, 7 retired elderlies, 4 house wives, 48 employees of compaines, 30 nurses, 4 laboratory technicians, 2 pharmacists, 7 house staff doctors, 12 chief doctors, 4 cases of hicking and 6 cases of 18 holes golf players. The daily walking steps were measured with pedometer in 167 times in total and following results were, obtained. 1. Bed rest patients ; less than 1000 steps/day 2. Retired elderly ; 2,724(2,150-3,500) steps/day 3. House wife ; 5,437(3,030-7,920) steps/day 4. High ranking, old clerk and chief doctor ; 5,000-6,000 steps/day 5. Ordinary non-active clerk and non-clerk employee ; 6,000-9,000 steps/day 6. common young active clerk and nurse ; 10,000-15,000 steps/day 7. Very active clerk and non-clerk employee ; 15,000(13,000-20,000) steps/day 8. Heavy worker ; more than 20,000 steps/day

There has been few papers regarding the pathologic changes of kidney induced by contrast media, especially in terms of iodine concentration or osmolarity. In order to evaluate histopathologic changes, a series of rat kidneys, after injection of iodinated contrast media, were examined. A total of 220 rats were divided into two groups: those given Urografin-60% by 6.3 ml/Kg(1840mg/6.3ml):those given Urografin-76% by 5ml/Kg(1850mg/5ml). (the same amount of iodine but at different iodine concentration). The kidneys were removed and microscopically examined on 1, 2, 3, 5, 7, 10th days, 2nd, 3rd, 4th, 6th and 12th weeks after injection of contrast media, respectively. The results were as follows: Renal pathologic changes induced by contrast media were congestion and ectatic change of the interstitial vessels, epithelial degeneration and necrosis of the collectiong ducts. Congestion of interstitial vessels and epithelial degeneration and necrosis of the collecting ducts were severe in the higher iodine concentration Urografin-76% group(2100 Osm/Kg H2O) than the Urografin-60% group(1500 Osm/Kg H2O). And above pathological changes persisted for 12weeks without significant interval changes. The authors conclude that the renal damage induced by ionic contrast media becomes more severe in higher concentrations or osmolarities in spite of the same amount of iodine and that the pathologic changes persisted until 12 weeks without improvement.

PURPOSE: The purpose of this study is to evaluate the diagnostic availability of the morphology of mitochondria to identify the nature or the origin of neoplasms. MATRIALS AND METHODS: We analysed two cases of ovarian malignancy- a case of malignant steroid cell tumor, unclassified and a case of metastatic carcinosarcoma from the adrenal cortex- which were difficult to identify the origin and the nature of the tumor for special staining, immunohistochemical and ultrastructural methods. RESULTS: To evaluate the nature or the origin of neoplasms, we performed immuno histochemistry for various antigens and special stains, however the specific diagnostic clues were not provided by these modalities. The ultrastructural characteristics of mitochondria of neoplastic cells showing tubular or tubulo-vesicular inner mitochondrial membranes provided diagnostic clues as a marker for steroidogenic potential. The morphology of mitochondria is related to the enzyme activity and steroid-biosynthetic capacity of cells. Especially, the inner mitochondrial membrane structure is believed to be related to the steroid biosynthetic activity. In hypofunctional state of corticosteroid productian, a reduced number of inner mitochondrial membranes showing tubular patterns is noted. In cantrast, the stimulation of steroidogenesis result in a progressive increase of mitochondrial membrane showing densely packed rounded vesicular patterns via tubulo-vesicular patterns according to the activity of steroidogenesis. CONCLUSION: The tubular, the vesicular and the tubulo-vesicular mitochondria will be valuable to identify the uncertainty of nature and origin of tumor as a stemidogenic.
